The word nose is commonly employed to describe that more or less prominent appendage on the front of the face. Physiologically the nasal passage leading backward from the nostrils is the region important to health. In addition although we do not usually think of the nose or nasal passages as a part of the phoniatric mechanism, they are important contributors to the hygiene of the respiratory tract as a whole and vital to normal voice production. Most people who depend upon the speaking or singing voice for the successful pursuit of their careers are well aware of the fact that nasal disease, even a simple common cold, impairs the voice. This chapter is devoted to a discussion of the physiological role of the nose in breathing, protecting the health of the airways, and supplementing the larynx as a resonator for sound (2, 3, 7, 8, 9, 10). Various problems of nasal disease and the voice will be discussed in Chaps. 9 and 10.
